....the agents environment. In their study the agents are homogeneous and there are no side payments. In other words, the goal is to share the work, not to pay for work. They also assume that each agent has su#cient resources to handle all the tasks, while we assume the contrary. Sandholm s agents [29, 28] redistribute work among themselves by a contracting mechanism. Sandholm considers agreements involving explicit payments, but he also assumes that the agents are homogeneous they have equivalent capabilities, and any agent can handle any task. Our agents are heterogeneous, and decide what ....

....used in AuctionBot [19] Our framework provides explicit market mechanisms which support more complex interactions. Furthermore, these market mechanisms enforce general market rules and social laws , such as government regulations, by which all participants must abide. Sandholm s agents [14, 15] redistribute work among themselves by a contracting mechanism. Sandholm considers agreements involving explicit payments, but he also assumes that the agents are homogeneous they have equivalent capabilities, and any agent can handle any task. We do not make any of these assumptions. Our ....

....proposed. However, a negotiation mechanism for a meta society requires that the agents assume, simultaneously, a dual behavior: self interested when dealing with others agents from external societies and cooperative within their society. This problem has already been addressed, but not solved, in [7]. In this paper we formalize a negotiation mechanism for automated contracting under such circumstances. The presented mechanism works among utility based agents and is supported by marginal utility calculations in order to guarantee the rational behavior of the society when reacting to its ....

....only for self interested agents. The use of a multi agent approach inside each enterprise rises some problems due to the duality of behavior that each agent must assume simultaneously: self interested when dealing with agents from other enterprises, and cooperative within the same enterprise [9]. This paper presents an electronic commerce framework for resource allocation in multi enterprise environments, where each enterprise s resources are controlled by a multi agent system, that overcomes the mentioned behavior duality problem. A similar version was already used in a practical ....

....and diverse; software agents should be prepared to inter operate in a changing and heterogeneous environment, and their social attitudes should change according to the problems being solved and the involved parties. According to their social attitudes, agents are usually divided into categories [3]: cooperative, if they try to maximize the welfare of a group of agents; self interested, if they only care about its own interests and welfare; and hostile or competitive, if the maximization of its welfare implies the decrease of the others satisfaction. An utility based agent acts according to ....

....3 THE AUTOMATED CONTRACTING MECHANISM 3. 1 Negotiation Protocols The main problem with the followed approach is the need for the agents to assume, simultaneously, two types of behavior: self interested, when dealing with agents from other enterprises, and cooperative, within the same enterprise [11]. To solve this problem two communication protocols are simultaneously used. Inside the enterprise, the agents cooperate trough a slight variation of the original Contract Net protocol (CNP) 13] For negotiations between different enterprises the CNP extension proposed in [10] is used. The ....

.... 8) IV Task Assignment The task assignment policy will be based on an announcement, bid and negotiation process inspired by the contract net al..gorithm proposed by Randall Davis in (Davis and Smith, 1983) Several extensions to the contract net have been already presented (Kuhn et al. 1993; Sandholm and Lesser, 1995a,b) but none of them including intercoalitions and intracoalitions negotiation. The modifications now introduced to the contract net tend to represent the market oriented behaviour intended for the agents in our system (Oliveira et al., 1996) with some similarities with the work (Fisher et al. ....

....problems involving goods with multiple units, and problems involving collective or public goods. For further discussion of this topic see [ Varian, 1995 ] While very simple yet powerful mechanism, the Vickrey mechanism may not be appropriate in all domains. For example, Sandholm and Lesser [ Sandholm and Lesser, 1995 ] have also argued that Vickrey mechanism is inadequate for domains where agents are bounded rational, i.e. where agents valuations are affected by time or by costly computational resources. Also in domains where an agent s marginal costs (and thus its reservation price) are determined by other ....
